From: Axel Davy Date: Wed, 2 Jan 2019 21:13:12 +0000 (+0100) Subject: st/nine: Ignore window size if error X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=86666f051e0cae96f2596cac05e3c3f394744149;p=mesa.git st/nine: Ignore window size if error Check GetWindowInfo and ignore the computed sizes if there is an error. Fixes a regression caused by earlier commit when using old wine gallium nine patches. Should also address a crash at window destruction.
